If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:
x + 40 + 40 = 180
x + 80 = 180 
x = 100
So the triangle's angles have measures of 40,40 and 100 degrees.
        
                    
             
        
        
        
Answer:
a = Negative one-fifth
Step-by-step explanation:
The given equation is :

We need to find the value of a.
Subtract 2/5 from both sides.

So, the correct answer is Negative one-fifth. Hence, the correct option is (b).
 
        
             
        
        
        
Answer:
y to 0.78y is a decrease
Step-by-step explanation:
y by itself can also be written as 1y, and 0.78y is less than 1, thus y to 0.78y is a decrease.

Answer:
x= -2
Step-by-step explanation:
6x+8=x-2
6x-x= -2-8
5x= -10
x= -10/5
x= -2
